Asynchronous update

leave a comment »

This concerns the problem I am facing in making web application. This is what I am going through : There is a server and, clients. As soon as the server gets a request it needs to send a message to n-1 || n clients to update an object. Polling is a solution but inefficient. So, I am finding a solution in which as soon as the server gets to know about the concerned event, all clients are acknowledged about it and to take appropriate action, like reloading the object or doing a local update to the object.

I do have a potential solution known by pubsubhubbub. Checking it out, hope it works.

Game of edges

leave a comment »

I don’t know why, but Sobel is not working. Detecting edges by Canny edge detector, by feeding morphed! images into it. Using convolution kernel, of aperture of size 3, is giving too much noise while 23 is too high. So, for the time beingĀ  settling for 15. Next step is to subtract the background. I wanted to detect foreground first and then use canny for edge detection, but the mentor says that both should be separate and parallel, and then join both threads for Hough transformation. More testing needs to be done. Booom!!!

A new service for ordering boooks

I was really impressed by what flipcart provides and the way it works. Similar to flipcart is www.jumadi.in . It is around 3-4 months old site that offers delivery of books and other stuff. To compare the two I checked the prices of some books ( like Computer Graphics by Peter Shirley and TAOCP – 1,2,3 ), and it was nice to see that prices at jumadi.in were lower than those at flipcart.
